# How to collect specified monomials in polynomial?

I'm not experienced in Wolfram Language, so couldn't you please help me with its syntax? Given the polynomial expression:

poly = 59049 Subscript[B, 1] Subscript[Abx, 1, 1] +
32805 Subscript[B, 1] Subscript[Abx, 1, 2] +
7290 Subscript[B, 1] Subscript[Abx, 1, 3] +
810 Subscript[B, 1] Subscript[Abx, 1, 4] +
45 Subscript[B, 1] Subscript[Abx, 1, 5] +
Subscript[B, 1] Subscript[Abx, 1, 6] -
59049 Subscript[B, 1] Subscript[Abx, 2, 1] -
32805 Subscript[B, 1] Subscript[Abx, 2, 2] -
7290 Subscript[B, 1] Subscript[Abx, 2, 3] -
810 Subscript[B, 1] Subscript[Abx, 2, 4] -
45 Subscript[B, 1] Subscript[Abx, 2, 5] -
Subscript[B, 1] Subscript[Abx, 2, 6] - 59049 Subscript[Aby, 1, 1] -
32805 Subscript[Aby, 1, 2] - 7290 Subscript[Aby, 1, 3] -
810 Subscript[Aby, 1, 4] - 45 Subscript[Aby, 1, 5] -
Subscript[Aby, 1, 6] + 59049 Subscript[Aby, 2, 1] +
32805 Subscript[Aby, 2, 2] + 7290 Subscript[Aby, 2, 3] +
810 Subscript[Aby, 2, 4] + 45 Subscript[Aby, 2, 5] +
Subscript[Aby, 2, 6]


and the list:

subs = {Subscript[Abx, 2, 4], Subscript[Abx, 2, 5],
Subscript[Abx, 2, 6], Subscript[Aby, 2, 1], Subscript[Aby, 2, 2],
Subscript[Aby, 2, 3], Subscript[Aby, 2, 4], Subscript[Aby, 2, 5],
Subscript[Aby, 2, 6]}


I need to collect the coefficients of monomials of the polynomial, that contain the variables from the list. So the answer should be:

{-810 Subscript[B, 1], -45 Subscript[B, 1], -Subscript[B,
1], 59049, 32805, 7290, 810, 45, 1}


I know how to do this using a lot of "For" and "If" constructions, but I know that it is not advisable because Wolfram Language has very powerful, beautiful and fast-acting built-in functions. Can you please help me and write, how to solve my problem with the most efficient way? Thank you!
